SAW-HANDLE.

SPECIFICATION forming part of Letters Patent No. 284,739, datedSeptember 11, 1883.

Application filed July 6, 1883. (Model.)

To all whom it may concern:

Be it known that I, HARRISON 1?. H001), a citizen of the United States,residing at Indianapolis, in the county of Marion, State of Indiana,have invented a new and useful Improved Saw-Handle, of which thefollowing is a specification.

My invention relates to that class of sawhandles in which a cylindricalhandle and the end of the saw-plate are clamped against an interveningsupport, adapted to fit the handle on one side and to receive the end ofthe saw- .plate 011 the opposite side, by means of a bolt hooked into ahole in the saw-plate and passing centrally through the interveningsupport and the handle, and threaded to receive a nut which is screwedon the bolt and against the handle.

The object of my improvement is to cause the screwing up of theclamping-nut against the handle to operate also to cause the interveningsupport to clamp strongly against the sides of the saw-plate, ashereinafter fully described.

The accompanying drawings illustrate my invention.

Figure 1 is a plan. Fig. 2 is a perspective of the clamping-jaws andtheir supportingbase separated. Fig. 3 is a plan showing a modificationof my device in which the base and one clamping-jaw are in one piece.Fig. 4 is a rear view of the base shown in Fig. 3.

A is the handle. I) is the saw. 0 (1, Figs. 1 and 2, are clamping-jaws,having each a fiat surface, 6, adapted to fit against the side of thesaw-plate, and having projecting lugs ff, adapted to support the end ofthe saw. Said jaws are recessed at g to allow the passage of theclamping-bolt h, which may be of the form shown, or of any suitable formadapted to engage the hole usually found near the end of a crosscut-saw,and to pass through the handle and receive a thumb-nut, i. i

j is a base-plate, having one side hollowed out to fit the cylindricalhandleA, and recessed in two directions at right angles to each other onthe other side, to receive the back edges of j aws c and d, and adaptedto support said jaws and to prevent their back edges from spreadingapart, and having a central perforation for the passage of theclampingbolt.

k Z are lugs projecting from the inner sides tion of the device as aclamp, but are for the purpose of preventing the jaws from becomingseparated from the handle =whenthe saw is removed.

The operation of my device is as follows: Base-plate j is placed on thehandle and jaws c and d erected on the plate, as shown. Theclamping-bolt is engaged with the saw-plate and inserted between thejaws and through the base-plate and handle and nut i screwed thereon, awasher, m, preventing the nut from chafing the handle. The end of thesaw-plate rests against lugs f f on each of the jaws, and as the nut isscrewed up the handle is clamped against the base-plate, and the jaws,each being supported at their back edges at a point outside of thelineof draft of the bolt and prevented from spreading by the base-plate, aredrawn together at their front edges, thus clamping the saw on both sidesand supporting the end at the same time. To change the handle from aposition parallel to the sides of the saw to a position at right anglesthereto, it is only necessary to loosen the nut sufficiently to raisethe clamps out of the recess in the base-plate and turn the handle andbaseplate.

In Figs. 3 and 4 I have illustrated a inodification of my clampingdevice, in which only one jaw is movable, the other jaw, 0, being formedintegral with the base-plate p, and unprovided with the lugs for thesupport of the end of the saw. The movable jaw is the same in allrespects as those shown in Fig. 1, and the operation is obviously thesame. For the purpose of changing the relative position of I has twohollows at right angles to each other to receive the handle, as shown inFig. 4.

I claim as my invention 1. In a handle-attaching device, the combination, with a handle, a nut, and a clampingbolt adapted to hook into orto be otherwise secured to a saw-blade, and threaded to receive saidnut, of a pair of converging jaws adapted to clasp the sides of thesaw-blade between them, and having projections 011 one 'or both of theiropposed clamping-surfaces to
